Fernando Torres and Andrés Iniesta were on target as Spain dominated Bolivia for a 2-0 win on Friday in the first of two international friendlies before their World Cup defence in Brazil.

Torres calmly stroked a 51st-minute penalty, earned by Javi Martínez, down the middle as the goalkeeper, Romel Quiñoñez, dived right.

Spain controlled play at the Sánchez Pizjuán Stadium but found it hard to convert against a well-organised Bolivian team before Iniesta charged forward to curl a shot round Quiñoñez in the 84th minute to seal victory.

Vicente del Bosque employed an experimental team, trying out different combinations with key Real Madrid and Atlético Madrid players still missing following the Champions League final last week.

The Spain coach will announce his 23-man squad for next month’s tournament on Saturday.
